CML Microcircuits, a provider of low-power semiconductors for Global wireless and telecoms markets has announced the launch of the new CMX7143, a highly integrated and adaptable multi-mode wireless data modem built on CML's proprietary FirmASIC component technology.

The NEW CMX7143 addresses the growing global market requirements for multi-mode wireless data connectivity, offering the ability to implement different wireless data schemes, with ease, when required. Wireless data scheme flexibility is a growing market requirement; particularly sort after by Machine-to-Machine (M2M) and Software Defined Radio (SDR) product manufacturers.

The CMX7143 initially offers 4-Level FSK operation, but the chip is configurable by swapping special Function Image data files, enabling the implementation of further wireless data schemes.

A Function Image can be loaded automatically from an external EEPROM or host microcontroller over the built-in C-BUS serial interface facilitating in-the-field upgrades if desired.

The CMX7143 is targeted at the expanding M2M, and SDR markets, along with Point-to-Point telemetry systems, traffic location systems and any other wireless data modem applications that require easily configurable multi-mode modem flexibility.

Offering a host of features including, 4.8kbps to 19.2kbps data rates, AFSD (Automatic Frame Sync Detection), flexible raw and packet data modes, soft decision decoding, RSSI processing (for Listen Before Transmit Applications) and a C-BUS serial interface to the host microcontroller, the CMX7143 provides everything that is needed in a wireless multi-mode data modem. Additionally, auxiliary ADCs with multiplex inputs, auxiliary DACs and auxiliary system clocks are provided to aid design and operational flexibility.

The NEW CMX7143 is available in a small, low power (3.0V to 3.6V with flexible powersave modes), 48-pin VQFN or LQFP package. An evaluation kit is available (PE0401), facilitating quick and easy design-in.
